In the depths of the sea, there is only one 'dong dong' sound left, and that is the Jiaolong.

"Release the water ballast chamber! Float the engine to its maximum! Get to the surface as fast as you can! Xingming instructed the other two to work quickly, and he also worked on the keyboard, looking at the disappeared expeditions 1 and 2 on the radar, adjusting the data.

The terrifying sound of "boom" was getting closer and closer, as if there was only a wall separating it.

Everyone sat at their posts and worked quickly, unaware of the approaching danger.

Suddenly, boom! The whole ship of Jiaolong swayed.

"Is there anything closer?" A man asked.

"I'm afraid the disappearance of Expedition 2 has something to do with this! Speed up the drain to the maximum! Turn up the engine's power to the max too! Turn off all the perimeter lights! Xingming quickly gave the order.

"Evacuate quickly! Jiaolong evacuated quickly! "Instructions came from El at the base headquarters.

At this time, there was a ding dong on the screen, and it was a document from the base headquarters? Xingming's skillfully operated keyboard opened the file. There were a few pictures inside, and everyone present was stunned when they looked at it!

After the crash of Expedition 2, they quickly sent a document to the base headquarters, which was the photos they took with the periscope, as well as the physical model fed back by the sonar, and the frequency and intensity of the sonar after the change.

The people at the base headquarters were in a cold sweat after reading it. The sound of help produced by the collision of sound waves and sound waves, the huge and terrifying big octopus monster!

Al quickly sent a copy of the information to the Jiaolong and told them to evacuate quickly!

Then the Jiaolong swayed back and forth! It's like you can't float! Entangled by a big octopus monster!

"We were caught by that big octopus?" A frightened man asked.

Xingming adjusted the frequency to the data, and the radar showed two dots, and those two dots were tightly together.

"Seems so." Xingming replied.

"Are we going to die here?" Another man said.

Suddenly, the Jiaolong shook even more, and a little electric spark fell off the wall sporadically.

A man angrily hammered his hands against the wall and cried out with tears in his eyes: "Damn! We haven't done anything yet! ”

Another man wailed.

The sound of "boom" frequently reached Xingming's ears.

Xingming was stunned at first, and then he became angry!

"Get out! Stop arguing!! Xingming shouted angrily, and the sound made the other two friends stop.

At this time, there was also a sound of "swish" in the depths of Xingming's brain! But he didn't realize it.

Suddenly, the three of them bent over slightly and felt the gravity strengthen? Wrong! It's they on the rise!

There was only one point left on the radar, and the other point was gone.

"What's going on? Are we on the rise? Xingming said and called up the data to check.

"We're floating!" A man cheered after reading the data, the speed was increasing, the speed was increasing.

"What's going on? Our big octopus let us go? A man was a little excited and said, after all, he had escaped from the hands of death.

"Maybe I was injured by the Expedition 2 and can't tie down another submarine." Another man explained.

Xingming pondered puzzled, is this the case?

"Check all system equipment for faults! We will now return to the base headquarters. Xingming said.

"Jiaolong, please answer when you hear it, please answer when you hear it." One woman repeatedly.

...........

"Jiaolong received!" Xingming said to Mai.

The people at the base headquarters breathed a sigh of relief, although the losses were still heavy.

The Jiaolong then withdrew to the water level.

Except for Xingming, who was slightly frightened and thinking, the other two were in deep panic, just brushing shoulders with death.

The base quickly dispatched several people and several doctors to pick them up.

After a cursory examination, the three were taken back to the break room.

There aren't many words in the whole process.

Al was in deep self-reproach in the control room of the base, and everyone else put down their work and remained silent.

...........

It didn't take long for Xingming to leave the lounge and go straight to the control room.

Xingming, who was originally quite calm, suddenly got angry and threw things in the control room, the display screen, and the keyboard all fell some.

"Stop!" Al shouted.

Xingming didn't listen at all and continued to fall, it wouldn't work if he didn't vent!

"We don't want something like this to happen!" Al took Xingming's collar and said angrily.

"We almost died!" Xing Ming said with red eyes.

There was silence for a while.

Xingming wiped the corner of his eyes, found a place to sit down, called up the keyboard and tapped it, a large amount of data was displayed on the screen, and he was turning up page by page. A radar map is then displayed on the screen, covered with many yellow dots, and moving slowly.

Everyone stared at all this blankly, not understanding what it meant.

"What is this?" A man asked curiously and suddenly.

"This is a big octopus on the bottom of the sea in the east." Xingming said.

"What??? So much? Suddenly, someone said in surprise.

"That's the number, so why can't our sonar system detect it in the first place?" Someone else asked.

"These shouldn't be ordinary octopuses, they can't be captured by the sonar system at a certain frequency, and the sound waves seem to pass directly through their bodies! No feedback! Xingming continued.

"How is this possible, and why is it detectable now?" The man continued.

"It's our dead teammates, the information they got with their lives. It must have been when he was dying that he noticed the strange sound, so he turned down the sonar until he could catch the presence of the big octopus. And it's not their massive bodies that are captured, but the low-frequency sound waves they emit. Xingming's eyes were a little serious, and he looked at the wriggling dot on the screen.

"What? You mean these octopuses are talking? Isn't this the same as what Ji Huan, who was shipwrecked before, said? The man asked, frightened.

"What are these big octopuses doing near the crystal? There are still a lot of them, like wanderers. The man continued.

"Prowler? This name is good. Or maybe they're new creatures we haven't discovered, or they're alien creatures inside the crystal. Xingming smiled bitterly.

"We're missing a point." Al pondered for a long time, and then said.

"There is some kind of force, or gravitational pull, in the crystals of the deep ocean. Unlike the one on the other side of the Lengshan Bomb Cave, its gravitational force is dozens of times greater than it, and we are careless, thinking that that force will not cause any big impact. Al continued.

"It's my foolish judgment that is the result of my loss." Al burst into tears as he spoke.

"It's irreparable." Xingming said calmly.

Everyone present also bowed their heads silently, silent in grief.
